A second day of violence in Vietnam has seen mobs singling out Chinese workers for attack, killing at least one and injuring dozens, as hundreds of Chinese nationals fled the country by land and air. A major foreign-owned steel operation was set ablaze in the country's north.
The unrest has been sparked by China's efforts to deploy an oil platform in disputed waters in the South China Sea, putting tensions on boil and spreading fear of a possible conflict between the neighboring countries that fought a brief border war in 1979.
Many potential new drugs look like they could be big winners — at least when judged by how well they work in mice or other lab animals. Over the years, there have been a number of promising cancer "cures," possible Alzheimer's treatments, and candidate drugs for holding back the ravages of various degenerative diseases.
But, time after time, these great promises fade away once the potential treatments are tried in people. There are lots of reasons for that. Humans aren't rodents, for starters.
As 92-year-old Betty Reid Soskin helped hash out plans for a new national park 13 years ago, this is what stuck in her mind: "What gets remembered is a function of who's in the room doing the remembering."
Office visits are the bread and butter of many physicians' practices. Medicare pays for more than 200 million of them a year, often to deal with routine problems like colds or high blood pressure. Most require relatively modest amounts of a doctor's time or medical know-how.
Octopus arms keep from getting all tangled up in part because some kind of chemical in octopus skin prevents the tentacles' suckers from grabbing on.
That was the surprise discovery of scientists who were trying to understand how octopuses manage to move all their weird appendages without getting tied in knots.
Unlike humans, octopuses don't have a constant awareness of their arms' locations. It's kind of like the eight arms have minds of their own. And as an octopus arm travels through the water, its neighboring arms are constantly in reach.
For a cake the Germans call "the king of cakes" and the Japanese call "the ultimate wedding cake," the baumkuchen doesn't really look like a cake or behave like one. But it more than makes up for its oddities with rich flavor, history and symbolism.
It resembles a hollowed cross-section of a craggy tree trunk, or a planet's rings, depending on how you make it. It can have up to 21 delicate, sugary stratums, which give it a light yet chewy texture.
This is TELL ME MORE from NPR News. I'm Celeste Headlee. Michel Martin is away. Nigeria has been in the news a lot lately. That's since the militant Islamic organization Boko Haram kidnapped hundreds of schoolgirls on April 15. Professed to be against Western education, Boko Haram took the girls away from their books and their teachers and have threatened to sell them as wives and slaves.
